[Numpy-discussion] BLAS not found in numpy 1.0b4

[Jonathan T. <jon...@ut...>]

When trying to install 1.0b4 I had trouble getting it to detect my
installed atlas.  This was because the shipped site.cfg had;

[atlas]
library_dirs = /usr/lib/atlas/3dnow/
atlas_libs = lapack, blas

but I had to change 3dnow to sse2 due to my current state of
pentiumness.  In any case it should probabally look in all the
possible locations instead of just AMD's location.

Cheers.
Jon.

"All possible locations" is pretty much impossible. There really isn't 
any choice but for individuals to customize site.cfg for their setup. 
that's why it's called "site".cfg.

I would like to see a pretty good collection of examples, most of them 
commented out, in there, however. i.e.:

## for AMD atlas:
#library_dirs = /usr/lib/atlas/3dnow/
#atlas_libs = lapack, blas

## for Fedora Core 4 sse2 atlas:
#library_dirs = /usr/lib/sse2/
#atlas_libs = lapack, blas

etc, etc.

I need this on fc5 x86_64

[atlas]
library_dirs = /usr/lib64/atlas
atlas_libs = lapack, blas, cblas, atlas

I think this should be automatic. Apart from debian, the /usr/lib64
directory is pretty much standard for 64bit linux distros.
